By default, Rowmote follows the preferences set in System Preferences for scrolling direction if you have an attached (or internal) trackpad.

Rowmote Pro 3.5.6 has a setting to control the scrolling direction; just use that. The below information is not needed.

Rowmote 3.5.6 is in review with Apple and will provide the same setting if you have purchased the Rowmote Pro upgrade. Until it is approved, a hidden preference can be used to change the scrolling direction.
